A stone is thrown outward, at an angle of 65 degrees with the vertical , into the river from the edge of the cliff that is 125 meters above the wate level at a velocity of 40 kilometers per hour. Use g = 9.81 m/sec2 . 1. Determine the distance from the edge of cliff to the point where the stone drops. Answer in 2 decimal places. 2. At what height above the water level will the stone starts to fall? Answer in 2 decimal places.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
